LinuxQuestions.org - config xorg for Acer c100 tablet device

I've been trying to get the tablet working on my Gateway M275 since the middle of August with no luck. Until to today that is, well still not working but close, very close...I hope.

Every FAQ that I read talks about how your tablet will be a device in "/dev/input/" but that's not true for my tablet. Today I bumped into something about it being on "/dev/ttyS0" if it is on COM1. I found my tablet to be on "/dev/ttyS1".

running "wacdump -f c100 /dev/ttyS1" I had to force it to c100 or it would time-out.
reports:
Model= Acer C100 Tablet PC Screen (Acer C100 huh? googled that to get the x.org lines i used.)
ROM=0.0-0 (is that right? all zeros?)
CLS=Serial
VNDR=Acer
Dev=c100
sub=c100

now that I know where my tablet is and wacdump spits out data when i move the pen around, everything should be peachy king after adding some lines to the X config right?

I added these line to the /etc/X11/xorg.conf
Section "InputDevice"
Driver "wacom"
Identifier "cursor"
Option "Device" "/dev/ttyS1" # SERIAL ONLY
Option "Type" "cursor"
EndSection

Section "InputDevice"
Driver "wacom"
Identifier "stylus"
Option "Device" "/dev/ttyS1" # SERIAL ONLY
Option "Type" "stylus"
EndSection

Section "InputDevice"
Driver "wacom"
Identifier "eraser"
Option "Device" "/dev/ttyS1" # SERIAL ONLY
Option "Type" "eraser"
EndSection

#this was added to the existing ServerLayout Section.

InputDevice "cursor" "SendCoreEvents"
InputDevice "stylus" "SendCoreEvents"
InputDevice "eraser" "SendCoreEvents"

After adding those lines, i restarted linux. Ubuntu 5.04 shutdown and came back up fine. But the pen still didn't work. I'm once again at a loss on what to do.

Can anyone point out what wrong. Or point me to a page somewhere.
